Fifteenth-century Constantinople. Present day Idaho. The future, and humanity’s last hope.

Across time and space, five young dreamers are bound by a single ancient text. Together, they tell a story of a world in peril; of the power of words, of resilience, and of hope against all odds.

The Pulitzer Prize-winning author of All the Light We Cannot See returns with a heart-breaking, magnificent epic of human connection and a love letter to storytelling itself.
